For this task, direct use of reduced-precision operations in existing algorithms will be explored. This is likely to
require the application of additional techniques to ensure robustness of the reduced precision in
some cases. For example, use of single precision values for particle position and direction with a
CSG geometry representation is problematic due to root-finding operations that can result in faulty
coincidence detection. We will develop and implement methods to mitigate these issues, e.g., by
employing a hierarchical geometry approach that is less susceptible to loss of precision.
